摘要： A fuel injector for internal combustion engines provided with a fuel feeding channel, the feeding channel having an axis and an injection outlet; an injection valve to control the outlet; an injection valve having a shutter arranged inside the feeding channel to define, within the feeding channel, a first fuel introduction section, the shutter being movable from and to a closing position along the feeding channel, which has a second section; and an annular sealing seat arranged on the feeding channel upstream of the outlet; an elastic member for normally keeping the shutter in the closing position; an actuator mechanism connected to the shutter to displace the shutter itself from the closing position and to an opening position of the outlet; and a hydraulic resistance that is provided along the feeding channel upstream of the annular sealing seat to balance the forces acting upon the shutter.
